Initial Code 
# Always be on the lookout for duplicated code. If you find yourself doing 
# asset.incomings.find(:all, :limit => 10) in multiple places, then perhaps you need to 
# pull that into a method of its own. Given the use of the magic number "10", it might
# not be a bad idea to do so anyway.

class Asset < ActiveRecord::Base
  has_many :incomings do
    def recent(count=10)
      find(:all, :limit => count)
    end
  end
end

# Then, you just have to do @asset.incomings.recent to get the first 10 items.
